Working Principle of TDA7365

The TDA7365 operates using a dual bridge-tied load configuration, providing higher output power from a standard 12V automotive supply. Each channel functions as a full-bridge amplifier, allowing the speaker to receive a voltage swing that is nearly double compared to a single-ended amplifier. The IC amplifies input audio signals and drives the speakers directly, offering clean output and reduced external component count. Built-in protection circuits ensure safe operation in harsh automotive environments.
